Title:
STABILIZED APMS-54 COMPOSITION AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH0624716
Kind Code:
A
Abstract:
PURPOSE: To obtain a stable APMS-54 compsn. containing boron, and to provide a producing method of this compsn.
CONSTITUTION: This invention provides a stable APMS-54 compsn. having d-distances shown in the table and containing 6 ppm by weight of external boron. In the producing method, an APMS-54 crystalline alumino phosphate compsn. is stabilized against deformation in the frame structure induced by heat. The compsn. shows the X-ray diffraction pattern having d-distances shown in the table. The compsn. is brought into contact with boric acid or its salt soln. at 20 to 90°C to incorporate boron at least by 6 ppm by weight into the APMS-54 compsn. Then the boron-contg. stabilized product is recovered.
